Drumless washing machine for washing textiles

Abstract

A drumless washing machine for washing textiles (18, 18a, 18b, 18c) has a detection device (28), which detects the degree of soiling of the textiles, and a plurality of washing chambers (40, 40-1 to 40-6, 40-k-1 to 40-k-8), the operation of which can be individually adapted to the textiles to be washed. After the degree of soiling is detected, a robot (44, 44-1, 44-2, 44'-1, 44'-2) arranges the textiles in the washing chambers so as to be spread out and without overlapping. A supply device (50) applies a washing liquid (W) to the textiles (18, 18a, 18b, 18c) spread out in the washing chambers (40, 40-1 to 40-6, 40-k-1 to 40-k-8), at least one property of the supplied washing liquid (W), in particular the temperature, amount, or detergent content of the washing liquid, being defined on the basis of the detected degree of soiling. The washing machine requires significantly less water, energy, and detergent than conventional washing machines and allows a mechanically very gentle washing process because only individual or very few textiles are washed individually in the washing chambers.

[0002] Drumless washing machine

[0003] for washing textiles

[0004] BACKGROUND OF THE INVENTION

[0005] 1. Field of the invention

[0006] The invention relates to a drumless washing machine for washing clothing and other textiles. Such washing machines can often also be used to wash non-textile parts of clothing, e.g., leather shoes.

[0007] 2. Description of the state of the art

[0008] Washing machines are household appliances used to wash textiles such as clothing, bed linen, or towels with water to which detergent is added. This process differs from dry cleaning, in which the textiles are cleaned in a waterless washing solution.

[0009] In conventional washing machines, the washing process begins with filling a drum located inside the appliance. Here, the soiled textiles are mixed with water and detergent. After the user has selected a suitable wash program, the washing machine controls the process automatically. First, water is let into the drum, where it mixes with the detergent. Then, the drum begins to rotate, which agitates the clothes and distributes the detergent evenly.

[0010] During the wash cycle, washing and rinsing phases alternate. In the rinsing phases, the dirty water is pumped out and clean water is added to remove detergent residue. After rinsing, the spin cycle begins, during which the drum rotates at high speed to force excess water out of the textiles. This process significantly reduces drying time. - 2 - 15.12.2025

[0011] Modern washing machines use sensors to monitor parameters such as water level, load size, and temperature to optimize energy and water consumption. Additional functions like pre-wash, short programs, and a delicate cycle allow for customized treatment of different fabrics and levels of soiling. After the wash cycle is complete, the washed and drained clothes can be removed from the drum and dried to remove any residual moisture remaining after spinning.

[0012] Washing machines with a drum offer many advantages and have therefore become established in the market. However, these appliances also have some disadvantages. These include a relatively high consumption of water, energy, and detergent. This is partly due to the fact that the selected wash program must always be based on the most heavily soiled textiles. Furthermore, textiles can be damaged or worn out over time due to the mechanical movement in the drum.

[0013] SUMMARY OF THE INVENTION

[0014] The object of the invention is to provide a washing machine that requires less water, energy and detergent than conventional washing machines and is gentler on textiles during washing.

[0015] This task is solved by a drumless washing machine for textiles, which has a detection device designed to determine the degree of soiling of the textiles. The washing machine also contains several washing chambers and a robot designed to arrange the scanned textiles in the washing chambers without overlap and spread out. Furthermore, the washing machine has a feed system for applying a washing liquid to the textiles spread out in the washing chambers. At least one property of the applied washing liquid, in particular a temperature, a quantity, or a detergent concentration, is defined depending on the detected degree of soiling. - 3 - 15.12.2025

[0016] The washing machine according to the invention requires significantly less water, energy and detergent than conventional washing machines, primarily for two reasons:

[0017] Firstly, the use of several individual and relatively small washing chambers allows the textiles to be spread out without overlapping before the washing liquid is added and the actual washing process begins. This allows the entire surface of the textile to be directly reached by the washing liquid – possibly with an additional turning action performed by the robot. This is a key difference compared to conventional drum-based washing machines, where the laundry must be continuously or repeatedly agitated in a large quantity of washing liquid to ensure that the liquid reaches all areas of the textiles. This conventional washing process not only requires a large amount of washing liquid to fill the drum, but also results in high mechanical stress on the textiles due to the agitation.The drumless washing machine according to the invention, on the other hand, only requires as much washing liquid as is necessary to thoroughly saturate the textiles. While additional movement or mechanical treatment of the textiles is not excluded, it is not normally required.

[0018] Secondly, the detection system allows the washing process to be individually adapted to the specific degree of soiling of the textiles. While conventional drum-based washing machines also use different washing programs for different types of textiles, and the intensity of the washing process can be increased for heavily soiled textiles, for example, by using a program with higher temperatures or adding more detergent, the most heavily soiled textile always ultimately determines the intensity of the required washing program. As a result, less soiled textiles are subjected to the same treatment as the most heavily soiled ones.

[0019] The inventive division into several washing chambers makes it possible to define a washing program optimally adapted to the degree of soiling for each textile. Preferably, each washing chamber contains only a single larger textile.-- 4 - 15.12.2025

[0020] This allows for the washing of small items or a few smaller textiles. For example, two identical garments with different levels of soiling can be washed in separate washing chambers under different conditions. This individualization of the washing process saves a significant amount of water, energy, and detergent overall.

[0021] In principle, it's possible to run the same wash program in all wash chambers simultaneously. However, it's more convenient if the wash chambers can be operated independently. This allows for a different wash program in each chamber, optimally adapted to the type of textile being washed there. Specifically, the wash chambers can be supplied with washing fluid at different temperatures via the feed system. This way, textiles placed in the washing machine can simply be fed one after the other into the next available wash chamber, where they can be washed using the program best suited to the detected level of soiling.

[0022] The detection system can be configured to record information about the type of fabric in addition to the degree of soiling. This includes, in particular, the material and color of the fabric. In many cases, it is also possible to use the detection system to record information printed on the garment's care label. The information obtained about the type of fabric, along with the detected degree of soiling, can be used to determine the optimal washing program for the specific fabric and then individually executed in the washing chamber.

[0023] The invention is based essentially on the advances made in robotics in recent years. Twenty years ago, it would have been unthinkable for a robot to grasp a piece of fabric and spread it out evenly and without major creases in a small chamber. With the help of cameras, whose images are evaluated by sophisticated image processing algorithms, and other sensors, it is now possible to have robots perform tasks that previously required human intervention with its image processing capabilities and manual dexterity. - 5 - 15.12.2025

[0024] To spread the textiles in the washing chambers, each chamber can be assigned its own robot. Assignment means that either a robot is permanently located in each washing chamber, or a robot dedicated solely to that chamber can be introduced to load and spread the textiles, and then remove them after the washing process is complete. Alternatively, several washing chambers can share one or more robots.

[0025] Just as it is now possible to clean painted surfaces of vehicle bodies without using brushes that damage the paint, textiles can also often be cleaned without mechanical action. This requires highly effective chemical cleaning solutions that are applied directly to the textiles.

[0026] In cases of very heavy local soiling, it may be necessary and more efficient for the washing machine to have a processing device that mechanically treats the surface of the textiles spread out and coated with washing liquid. Such a processing device could, for example, include a robot arm with a rotatably mounted ball at its end. Using this ball, the robot arm can treat the surface of the spread-out textile by applying a predefined pressure, thus bringing the washing liquid into even more intensive contact with the textile fibers. Preferably, this mechanical treatment is performed only in areas with particularly heavy soiling. In this way, the mechanical stress on the textile is reduced to the absolute minimum.

[0027] The processing unit can also be formed by the robot itself, which is used to spread the textiles in the washing chamber. To process the surface of a textile, a robot gripper either moves directly across the surface of the textile, or the gripper first grasps an additional processing element, such as the aforementioned ball. Alternatively, the gripper can be replaced with such a processing element, for which the robot hand must have a suitable coupling. - 6 - 15.12.2025

[0028] In one embodiment, the internal dimensions of the washing chambers can be changed by moving the chamber walls. This allows the size of the washing chambers to be adapted to the dimensions of the textile being washed, resulting in even more efficient use of water and energy.

[0029] In one embodiment, each washing chamber has a base. The robot is designed to spread the textiles out on the base of the washing chambers without overlapping. This results in a horizontal alignment of the textiles during the washing process, which is advantageous for a particularly even washing result. Such horizontally aligned washing chambers can then be arranged one above the other in the washing machine.

[0030] Alternatively, the washing chambers can be vertically oriented and arranged horizontally side by side in the washing machine. This allows the textiles to be hung freely in the chambers. This makes it easier to spread the textiles out, as gravity assists in pulling them apart vertically. However, hanging the textiles can be difficult in some cases; furthermore, the washing liquid then runs down the fabric, which can lead to an uneven wash.

[0031] The detection device can include a stationary or movable camera. Using (possibly AI-supported) image recognition algorithms, the degree of soiling can then usually be detected non-contact by observing a discoloration. Alternatively or additionally, a scanning detection device can be used, which is designed to successively scan the surface of the textiles with a detection beam.

[0032] The soiling level assigned to the textiles by the detection device can be a simple numerical value, e.g., a number between 0 and 10. However, the soiling level can also include more complex information. If the detection device is configured to identify areas of increased soiling on the textiles, these areas can also be stored in the soiling level. - 7 - 15.12.2025

[0033] Preferably, the washing machine has a control device that is designed to control the feed device in such a way that areas on the textiles with increased soiling are washed with more and / or hotter washing liquid and / or with more intensive mechanical treatment.

[0034] The washing machine can have its own wastewater treatment system, designed to purify the dirty wash liquid drained from the washing chambers and make the purified liquid available for reuse. Reusing the wash liquid further reduces fresh water consumption. In one embodiment, the washing machine has a feed opening and a conveyor belt designed to convey garments, fed into the washing machine by an operator through the feed opening, to the detection unit. The detection unit can then include a robot designed to spread the textiles out on the conveyor belt without overlapping. The conveyor belt then guides the textiles past a fixed detection unit, creating a scanning effect.

[0035] The detection device can perform various other tasks. In particular, it can be configured to generate an alarm signal if it detects items not intended for the washing process in the textiles and / or damage to the textiles. It can also be configured to identify the brand of the textile. If the washing machine has a data interface and damage is detected, information regarding the brand of the damaged textile can be transmitted to an app via this interface. The app can then, for example, offer household members deals for purchasing the same or a similar textile.

[0036] To wash trousers particularly efficiently, at least one washing chamber can have a clamping device for trousers, which has two elements that can be inserted into the trouser legs and are arranged to rotate together around a turning axis. This allows the washing liquid to reach the entire surface of the trousers without the need for the robot to turn them over in a time-consuming turning process. - 8 - 15.12.2025

[0037] The washing chambers can also include fixing devices to secure textiles spread out within them. This is particularly useful if the textile is also to be mechanically processed. The fixing devices can be passive, meaning they have a spring action, allowing the textile to be inserted or placed inside. However, active fixing devices are also possible, which use a power-operated actuator to secure the textile.

[0038] Preferably, a monitoring device is provided that is designed to check the result of the washing process and, if the result is unsatisfactory, to initiate another washing cycle. This allows the washing process to be carried out initially with a small amount of relatively cool water and a small amount of detergent. If the monitoring device determines that the washing result is unsatisfactory, the washing process can be repeated with more and / or hotter water and / or more detergent.

[0039] The inspection device can be designed in the same way as, or even be formed by, the detection device. However, if a central inspection device is provided, textiles must be transferred to a free washing chamber again if the washing result is unsatisfactory, which is cumbersome. Therefore, preferably, each washing chamber contains its own inspection device.

[0040] The washing machine may also have a drying unit designed to dry the textiles after the washing cycle. This drying unit may, for example, include a roller that mechanically squeezes the washing or rinsing liquid out of the textiles. If the drying unit also has a radiant heat source designed to direct heat radiation onto the textiles, this can remove any remaining residual moisture.

[0041] Here too, it is possible either to provide a central drying chamber equipped with the drying unit, or to equip each washing chamber with its own drying unit, so that the textiles can remain in their respective washing chamber to dry after the washing process. - 9 - 15.12.2025

[0049] DESCRIPTION OF PREFERRED EXAMPLES

[0050] 1. First embodiment

[0051] Figure 1 shows a washing machine, designated overall by 10, according to a first embodiment in a schematic side section.

[0052] The washing machine 10 has a housing 12 with a top cover 14, on which a filling funnel 16 is formed. Textiles 18 placed there fall through a feed opening 20 into a collection chamber 22, where the textiles 18 are collected.

[0053] In the illustrated embodiment, the collection chamber 22 has a removal opening 24 on the side wall shown on the left, through which the textiles 18 collected in the collection chamber 22 can be individually removed. With the aid of a movable device, the textiles 18 can be removed individually. (10 - 15.12.2025)

[0054] Stamp 25 allows the textiles 18 in the collection room 22 to be pushed towards the removal opening 24 in a sensor-controlled manner.

[0055] Adjoining the collection chamber 22 on the left is a detection chamber 26 with a detection device 28, which comprises a belt conveyor 30, a sensor 32 (designed as a camera) carried by an adjustable arm 31, and three robots 34-1 to 34-3. Each robot 34-1 to 34-3 has a movable arm 36, which carries a gripper 38 at its end. The robots 34-1 to 34-3 are attached to an adjustable ceiling 35 in a manner not shown in detail, such that they can each be moved in all three spatial directions x, y, z. This allows the grippers 38 to detect textiles 18 at any location on the belt conveyor 30. For example, this makes it possible to position the three robots 34-1 to 34-3 side by side (i.e., with the same x-coordinate and thus perpendicular to the plane of Figure 1).

[0056] The robots 34-1 to 34-3 are tasked with removing a textile 18 from the collection chamber 22 via the removal opening 24 and spreading it flat on the conveyor belt 30 without overlapping any other textile. The spread-out textile 18 is guided past the sensor 32 by the conveyor belt 30, which performs movements along the y-direction. With suitable coordination with the control system of the conveyor belt 30, the entire surface of the spread-out textile 18 can thus be scanned with a meandering scan path.

[0057] Sensor 32 is used to detect soiling of the textile 18 and to assign a degree of soiling. To do this, sensor 32 detects, in particular, local color changes from which conclusions about the degree of soiling can be drawn. Furthermore, the sensor can detect, for example, whether the textiles contain items not intended for washing, such as paper tissues or sweets. In such cases, the detection device 28 can trigger an alarm signal. The same applies if the detection device 28 detects a tear or other damage to the textile 18 that would be exacerbated by a subsequent washing process. This information is transmitted via a radio interface 39 to an app, which an operator... 11 - 15.12.2025

[0058] informs you about the detected damage and, if desired, can also provide you with web-based offers for a new textile.

[0059] When the scanning process is complete, the textile 18 is lifted and turned over using the robots 34-1 to 34-3 in order to scan the back of the textile using the sensor 32.

[0060] Once the entire scanning process is complete, a soiling level is assigned to textile 18. Additionally, locations where particularly high levels of soiling were detected can be recorded.

[0061] The textile 18 is now placed in one of six washing chambers 40-1 to 40-6. In the illustrated embodiment, all washing chambers 40-1 to 40-6 have the same dimensions, so it does not matter which of the washing chambers 40-1 to 40-6 the textile 18 is placed in, provided the chamber is free. For the sake of simplicity, it is assumed here that the upper washing chamber 40-1 is free, which is why the textile 18 is placed there.

[0062] In the illustrated embodiment, the washing chambers 40-1 to 40-6 are not only the same size but also identical in construction. Each washing chamber 40 has a floor 42, two robots 44-1 and 44-2, an inspection device 46, a movable roller 48, a feed device (designated 50) for supplying washing liquid, and an arrangement of heat radiation sources 52. The washing chambers 40 each have a flap 54 and 56 on their front and rear sides, respectively, for loading and unloading. The flaps 54 and 56 are hinged in opposite directions, so that the flap 54 shown on the left opens upwards and the flap 56 shown on the right opens downwards.When the flap 54 shown on the left is opened, a textile 18 falls from the conveyor belt 30 onto the flap 54 due to gravity and can be picked up there by robots 44-1 and 44-2 and spread out on the floor 42 of the chamber 40-1 to be loaded. In chamber 40-1, a textile 18a is almost completely spread out, while a second textile 18b is currently on the flap 54 and is being pulled into the washing chamber 40-1 by robot 44-1. If a larger or- 12 - 15.12.2025.

[0063] Once several small textiles 18 are all spread out on the floor area 42 of the washing chamber 40, the washing process can begin.

[0064] In the second washing chamber 40-2, such a washing process is currently taking place. For this purpose, the feeder 50 applies a washing liquid W to the textiles 18 spread out there. The washing liquid W is supplied via a feed line 60, enters the washing chamber 40-2 through nozzles 62, and sprays the textiles 18 spread out on the floor surface 42. The outlet nozzles 62 are individually controlled by a control unit 63 so that as little washing liquid as possible reaches areas of the floor surface 42 that are not covered by a textile 18. The feed line 60 of the feeder 50 is connected by a line (not shown) to a fresh water treatment unit 70 located at the bottom of the housing 12, in which fresh water drawn from a fresh water connection 71 is heated and mixed with a detergent.

[0065] Fresh water is also supplied via the feed unit 50 to rinse the textiles and remove detergent residue. If necessary, the roller 48, which can be moved along the x-direction, can be moved over the textiles 18 to squeeze out the absorbed washing liquid and then replace it with clean rinse water.

[0066] Once the inspection device 46 has determined that all textiles in washing chamber 40-2 are clean, the actual washing process is terminated. This check of the degree of soiling using the inspection device 46 is currently taking place in the third washing chamber 40-3. The inspection device 46 can be constructed similarly to the detection device 28 and includes a sensor 51 with which the soiling of the textiles can be detected. If, however, the result of the washing process is insufficient, it is repeated, possibly using a washing liquid with a higher temperature and / or more detergent.

[0067] Dirty washing liquid and rinse water are drained through openings in the base surface 42, which are only shown in Figure 5, and fed to a wastewater treatment unit 72. There, the wastewater is filtered so that a portion is returned via a feeder line 74. 13 - 15.12.2025

[0068] The fresh water can be reused via the fresh water treatment plant 70. The more heavily polluted remainder of the wastewater is discharged to the outside via a wastewater connection 76.

[0069] The textiles 18 can also be dried in the washing chambers 40. In the fourth washing chamber 40-4, such drying takes place in a first stage. For this purpose, the roller 48 moves over the textiles and presses out the rinse water contained within them. This process can be repeated, if necessary, with increasing the contact pressure of the roller 48.

[0070] The second drying stage consists of irradiating the textiles with heat radiation generated by the heat radiation sources 52. This final drying using heat radiation takes place in washing chamber 40-5. For faster and more energy-efficient drying, the textiles 18 can be turned once or, if necessary, several times using the robots 40. To determine the degree of drying, additional sensors, known per se, can be arranged in the washing chambers 40 (not shown).

[0071] After drying to the desired degree of dryness, the textiles 18 are removed from the respective washing chamber by robots 44. This process is illustrated in washing chamber 40-6 shown below. For this purpose, the right flap 56 is opened so that the robots 44 can remove the textiles they have picked up from washing chamber 40-6. From there, they fall into a further collection chamber 78 at the bottom of the housing 12. From there, they can be removed by an operator via an access opening 80.

[0072] Figure 2 shows a schematic horizontal section of the washing machine 10. It can be seen that several wash chambers are arranged not only one above the other, but also side by side. In the illustrated embodiment, elongated wash chambers 40-k-1 to 40-k-4 are arranged in each of the N = 6 levels, where k = 1...N. Thus, a total of N x M = 24 wash chambers 40 are available.

[0073] In the illustrated embodiment, the side wall extending along the x-direction between the washing chambers 40-k-1 and 40-k-2 is displaceable along the y-direction. - 14 - 15.12.2025

[0074] as indicated by a double arrow. This allows the internal dimensions of the two washing chambers 40-k-1 and 40-k-2 to be changed within the limits indicated by the dashed lines. This can be useful when washing particularly large textiles such as towels.

[0075] Figure 3 shows a variant corresponding to Figure 2 in which, instead of M = 4, washing chambers 40-k-1 to 40-k-8 are arranged in the plane k.

[0076] Differently sized washing chambers 40 can be arranged on different levels k. This allows for the very different dimensions of the textiles to be washed to be taken into account.

[0077] 2. Further examples of implementation

[0078] Figure 4 shows a washing chamber 40' in which only one robot 44 is arranged. To place the textiles 18 into and remove them from the washing chamber 40', two further robots 44'-1 and 44'-2 are assigned to the washing chamber 40', which, however, are not inside the washing chamber 40', but are attached outside of it to the housing 12 of the washing machine 10.

[0079] Figure 4 also shows the openings 82 in the floor surface 42 of the chamber 40', through which used washing liquid and rinsing liquid can flow out and be supplied to the wastewater treatment unit 72 via a discharge line 84.

[0080] The washing chamber 40' shown in Figure 4 differs further from the washing chambers 40 shown in Figure 1 in that it contains a processing device 86. This device is designed like the robot 44, but instead of a gripper, it carries a rotatable ball 88, which is rolled over the textile 18 for the mechanical treatment of heavily soiled areas. This achieves a similar effect to that obtained by handwashing with the ball of the thumb or the back of the hand.

[0081] In the variant shown in Figure 5, the washing chamber 40" has only one opening, which can be closed with a sliding door 90. A clamping device 94 is attached to the opposite end face 92, which holds two rods arranged one behind the other in the z-direction. 15 - 15.12.2025

[0082] The figure comprises two rods, of which only the front rod 96, pointing towards the viewer, is visible in Figure 5. The two rods 96 can be rotated about a common axis 100 by means of a reversing device 98.

[0083] The clamping device 94 serves to clamp a pair of trousers 18c inserted into the washing chamber 40". Each trouser leg is pushed onto one of the rods 96 by means of the robots 44. By means of a fixing device 102, which can be designed as a pressure plunger adjustable by means of an actuator, the trousers 18c can be fixed to the rods 96 during the washing process. By means of the turning device 96, the trousers 18c can be turned over so that the back of the trousers 18c can also be washed in the manner described above by supplying washing liquid.
